BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 294,504, dated March 4,1884.

' Application ined December 6,1883. (No modem clare the following to bea full, clear, and eX- act description yof the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention has for its object to provide an improved and novelconstruction of that class of metallic button-fasteners which arecomposed of a fiat table or plate having downwardly-projecting prongs,one-prong of which is formed with a loop to receive the shank 'of thebutton, and all of the said prongs being adapted to be passed downthrough a fabric and clinched upon the under surface thereof to securethe button thereto; and my improvements consist, essentially, in formingthe metallic fastener or connection from a blank cut from stock rolledin a peculiar shape, being thick at the center and tapering from thenceto a thin edge at each side, all as will be hereinafter more fullydescribed, and spe'- ciiically pointed out in the claims. Y

In the accompanying drawings, Figure l rep- 'resents an enlargedperspective view of my shape shown'in cross-section in Fig. 4, thecenedge at each side of the same, as shown intral portion of said stockbeing of a suitable thickness, and tapering from thence to a thin Figs.3 and 4. The blank A, cut from said stock, is preferably of the shapeshown in Fig; 3, with one prong, a, lat one side and two prongs, b, atthe opposite side of the intermediate or central table or plate, c, asshown, although the number and location of the said prongs may bechanged or increased or decreased at pleasure, the main object, ineither case, being to provide a central table of a greater thicknessthan that of the prongs which taper froln said central plate out to athin sharp edge. The complete fastener is formed from the blank A byfirst bending the prong a into a loop to receive the shank of thebutton, and

then bending said prong down at right angles to the central table orplate,` c, the opposite prong or prongs, b, being also bent down atright angles to said plate to form the complete fastener, as shown-inFigs. l and 2.

By means of my improved construction I` am enabled to provide abutton-fastener which is not only strong and durable, but which can beproduced at a much less cost than where each separate fastener has to bemanipulated by 'expensive machinery to thin or flatten the lower ends orpoints of the prongs, as has been the practice heretofore.

Having thus described my invention, what I claim as new and useful is 1.As an improved article of manufacture, the herein-describedbutton-fastener, formed from the blank A, having a portion thickened ata central line,.from which the prongs a b are gradually reduced inthickness outward to their extremities, and which are bent at rightangles, substantially as and for the purpose specified. p

2. The blank A, formed as described, with a portion thickened at acentral line, vfrom which the prongs a b are gradually reduced inthickness outward to their extremities, substantially as and for thepurpose specified.

In testimony whereof I affix my signature'in presence of two witnesses.
